TO ALL WHOM IT MAY CONCERN:

Be it knownthat I, CHARLES l). MILLER, of West Meriden, in the county ofNew Haven, and State oi Connecticut, have invented a new Improvement inCarriage Shackles; and I do hereby declare the following, when taken inconnection with the accompanying drawings, and the letters of referencemarked thereon, to he a full, clear, and exact description of the same,and which said drawings constitute part of this specification, andrepresent, in

Figure 1, a side view.

Figure 2, a top view.

Figure 3, a longitudinal central section.

Figure 4, the same, the parts in difl'erent position.

Figure 5, the perspective view of the pivot; and, in

Figure 6, a detached view of the part B,

This invention relates to an improvement in the attachment of" the poleor.shaft to carriages, and consists in the peculiar construction andcombination of the parts whereby the use of rivets, belts, or otherdetachable parts is entirely avoided To enable others skilled in the artto construct and use my improvement, I will proceed to describe the sameas illustrated in the accompanying drawings.

A is the clip or strap bywhich the coupling is attached to the carriageaxle; B the strap to which the pole or shafts are fixed. The end of thestrap A forms a socket, G, into which is closely fitted a pivot, D. Uponthe upper side of the socket C I form a slot, (Z, and in the pivot D acorresponding slot, a, (see figs. 3 and 5,) so that when the pivot D isin the position denoted in fig. 4 the slots in the pivot and socketcorrespond. The strap B is formed with two heads, E, about the size ofthe socket G, or larger than pivot D, and so as to enclose the socket C,as soon in fig. 2. Between the two heads extendsa bar, f, (see fig. 6,)which said bar is formed to set through the slot :2 in the socket, andfit closely into the slotat in the pivot D, as seen in figs. 3 and 4.

To insert-the part B into thesocket so as to' attach the pole or shaftto the axle, raise the part B to the position denoted in fig. f}, andinsert the barf'through the slot (Z into the pivot; then turn the part Bdown, as seen in fig. 3, which is about the position for general use. Toprevent the pivot D from being displaced in the absence of the pole orshaft connections, I form a groove, a, partially around the said pivot,as see figs. 3 and 5, and into the socket O I place a pin, 1', whichenters the said groove in the socket, and prevents its displacement, andalso serves the important purpose of stopping the said pivot when at theproper position for the insertion or' removal of the pole or shafts, asseen in fig. 4. To prevent rattling, I insert in the slot a in thcpivot,and beneath the barf, a thin piece of India rubber, or othersimilarmaterial, as seen in figs. 3 and 4.

I do not hroadly claim a carriage shackle when constructed with a slotand pivot, so that the shafts may he attached or detached by raising toa given point, as such is not new, as may be seen in the patents to E.W. Seymour, February 2-5, 1862, and L. T. Hazen, September I6, 1862.

Having, therefore, thus fully described my invention, what I claim asnew and useful, and desire to secure by Letters Patent, is

1. The combination and arrangement of the bar f, extending between theheads E, with the socket C, and pivot D, each constructed with a-slottheir entire length, to receive the bar f, and so as to operatesubstantially in the manner herein set forth.

2. The arrangement of the groove 7t on the pivot D,.and the pin 2' incombination with the socket C, substantially as and for the purposespecified.
